NEW QUESTION # 20
Users report that traffic is negatively affected every time a BIG-IP device fails over. The traffic becomes stabilized after a few minutes. What should the BIG-IP Administrator do to reduce the impact of future failovers?
Answer: C
Explanation:
When traffic "stabilizes after a few minutes" following a failover, it points to a network-level performance issue involving ARP cache on upstream routers and switches. Each BIG-IP interface has a unique hardware MAC address. During failover, the Standby device takes over the floating IP address, but the upstream switch still associates that IP with the MAC of the now-offline device. Traffic is lost until the switch learns the new MAC or its ARP entry expires. "MAC Masquerading" solves this by creating a shared, virtual MAC address for the floating traffic group. This virtual MAC is used by whichever device is currently active. Because the MAC address for the virtual server IP never changes from the perspective of the network, the upstream devices do not need to update their ARP tables. This troubleshooting solution eliminates the delay associated with failover, providing a seamless transition and ensuring that application traffic flow is not disrupted when the BIG-IP HA state changes.
NEW QUESTION # 21
When using the "Manual Resume" feature in BIG-IP, what state will a pool member remain in after a health monitor failure, even if health checks begin to pass again?
Answer: D
Explanation:
Comprehensive and Detailed Explanation From BIG-IP Administration Support and Troubleshooting documents: The "Manual Resume" feature is a safety mechanism used when a pool is not working as expected due to flapping services or unstable backend applications. Normally, when a health monitor fails, the pool member is marked "Offline" (Red), and when the monitor passes, it automatically returns to "Available" (Green)47. However, if "Manual Resume" is enabled, the BIG-IP will not automatically put the member back into rotation after a failure48. Even if the health check begins to pass again, the member remains in an
"Offline (Disabled)" state49. This requires an administrator to manually intervene and re-enable the member.
This is a common point of confusion when troubleshooting; a member may show passing health checks but still not receive traffic because it is waiting for a manual administrative "resume" command. This feature is intended to prevent "unhealthy" servers from receiving traffic until an engineer has confirmed the root cause of the initial failure was resolved.
NEW QUESTION # 22
Clients report that they cannot reach the virtual server vs-production on port 80, but are able to ping the virtual server address. The configuration is shown below:
Plaintext
ltm virtual vs-production {
destination 10.99.20.50:http
ip-protocol tcp
mask 255.255.255.255
profiles {
http {}
tcp {}
}
source 192.168.0.0/16
translate-address enabled
translate-port enabled
vlans {
external
}
vlans-enabled
}
What is the cause?
Answer: B
Explanation:
The issue is caused by the Source Address restriction configured on the virtual server.
Source Filter: The configuration contains the line source 192.168.0.0/16. This acts as an implicit Access Control List (ACL). The virtual server will only accept and process TCP connections if the client's source IP address falls within the 192.168.x.x range.
Why Ping Works: ICMP (Ping) is handled by the Virtual Address object, not the Virtual Server object. Unless ICMP is specifically disabled on the Virtual Address, it will respond to pings from any subnet, even if the Virtual Server itself is restricted by a source filter or is even disabled.
Evaluation of Other Options:
Disabled (Option A): If the VS were disabled, the configuration would typically show disabled or state down, and the symptoms would be similar, but the source filter is a more specific "misconfiguration" in this context.
Port 80 (Option C): The configuration destination 10.99.20.50:http explicitly confirms it is listening on port 80.
Unallowed Subnet: If a client from a different network (e.g., 10.10.1.5) tries to connect, the BIG-IP will silently drop the connection or send a reset because it does not match the defined source criteria.
NEW QUESTION # 23
A BIG-IP Administrator uses backend servers to host multiple services per server. There are multiple virtual servers and pools defined, referencing the same backend servers. Which load balancing algorithm is most appropriate to have an equal number of connections on each backend server?17
Answer: C
Explanation:
When load balancing is not working as 23expected and connections appear skewed across physical hardware, the administrator must distinguish between "member"24 and "node" level balancing. A "member" refers to a specific IP and Port combination (e.g., 10.1.1.1:80), whereas a "node" refers to the underlying IP address (10.1.1.1) regardless of the port25. If a single server hosts multiple services (Web, FTP, API) across different pools, using "Least Connections (member)" would only balance connections within each individual pool26.
This could lead to a scenario where one server is overwhelmed because it is winning the "least connections" count in three different pools simultaneously. By selecting "Least Connections (node)," the BIG-IP tracks the total number of concurrent connections to the physical IP address across all pools it belongs to27. This ensures that the administrator can maintain an equal distribution of work across the hardware, preventing performance degradation on backend servers that host multiple application services.
NEW QUESTION # 24
A BIG-IP Administrator plans to upgrade a BIG-IP device to the latest TMOS version. Which two tools could the administrator leverage to verify known issues for the target versions? (Choose two answers)
Answer: D,E
Explanation:
Before upgrading a BIG-IP system to a newer TMOS version, it is critical to review known issues to avoid introducing instability or regressions.F5 Bug Tracker (Option B)is a primary resource for this purpose. It allows administrators to search for documented software defects by TMOS version, module, symptom, or bug ID. Using Bug Tracker, an administrator can identify unresolvedissues, fixed bugs, and behavioral changes that may affect their specific deployment, such as traffic handling, high availability, or module-specific functionality. This directly supports proactive troubleshooting and informed upgrade planning.
F5 iHealth (Option D)is another essential tool used during upgrade preparation. iHealth analyzes uploaded UCS or QKView files and correlates the device configuration and software version with F5's known issues database. It provides actionable reports highlighting critical defects, upgrade risks, interoperability concerns, and recommended target versions. iHealth is especially valuable because it contextualizes known issues based on the actual configuration running on the device.
